DRIVING CONN ECTION Application led June 23, 1915.

7b all 'whom it may concern:

Be it known that we GnononG. Minne, a citizen of the United lates, and a resident of Rye, Westchester county, New York, and VILLAno F. RICHARDS, a citizen of the United States, and a resident of Bull'alo, county of Erie, State of New York, have iiivented certain new and useful Improvements in Driving Connections, of which the following is a specification.

The invention relates Lo improvements in driving connections, and is especially applicable to the driving of dynamo electric iriachines from car axles, although il muy be found useful in other situations. The object of the in venrioii is to improve upon the driving connection shown iii U. S. application for Letters Patent Serial No. 814,055, filed January 24, 1914.

More specific objects, features and advantages will clearly ap ear Vfrom the detailed description given begon', taken in connection with the accompanying sheet of drawings which forms a partI of this specification.

ln the drawings, Figure 1 illustrates a dynamo driven from :i car axle with the iinproveineiits in one form applied thereto;

Fig. 2 is a plan view of the driving connection, certain parts'being broken away or shown in section to more clearly illustrate certain features;

Fig. 3 is a vertical section through the driving connection; taken on the line 2-2 of Fig. 2 and the line 33 of Fig. 4; and Fi 4 is a section taken on the lino 4.---4 of Fw. 3 and the line 5-5 of Fig. 2.

Re errin to Fig. 1, 1 represents a car body to wiich is Asecurely attached a dynamo 2. Part of one of the enr trucks is shown at 3 provided with car |wheels 4 and an axle 5. Contained in a casing G is any suitable fearing for driving a shaft 7, tho outer en of the casing bein supported from a cross bar S of the truck y means of` a flexible connection 9. A shaft 10 is conncctcd at one end tothe shaft 7 by'nieans of a universal joint 1l and atts otherto the shaft 12V by means of u universal )oi'it 13. The shaft 12 is journaled in a frame 14 rigid'- with the dynamo v2. T hc dynamo shaft is shown at 15 and has rigidly secured on its end a disk 16.

Referring. more' particularly to Figs. 2, 3 and 4, the driving shaft 12 has secured Specification of Letters Patent.

thereto by a key 17 and nuts 12 and 19, a driying iiicinber 20 comprising a recessed casinv .gnicuiber having a central stud 21 boredalo accommodate the end of the shaft 12. 'llie casing is formed with an integral outer flange 22 to the edge of which are bolted two pairs of semi-circular plates 23 and 24, respectively, by means of bolts 25. Each pair foini's a circular disk plate divided iii two pieces as indicated with re- ,shaft 12 and nuts 18 and 19. The driven member 2T is provided with a flange 29 1ocated on the inside of the plates 23 so that the nioinbcr 27 is prevented from slipping oil' oi the stud 21 after the plates 23 and 2-1 are bolted in place. A sning 30 is coiled about the axis of the stu 2] and shaft 12, and about the inenibcr 27 inside the flange 29. One end of the spring 30 is connected to the member 27 by a pin 3l locatcdin a recess in the member 27. A flange piece 32 is secured to the inner end of member 27 by means of pins 83 so that the convolutions of the spring 30 are held in place on the member 27 between the flange piece 32 and flange 29. Extending about. and concentric with 'the member 27 and shaft 12 is a circular member 34, to which the outer end of the spring 30 is connected by means of a pin 35 .situated in a recess therein us shown in Fig. 4. The member 34 is recessed along the cen-A bers 20 and 34 in case the holes 37 and the side of the casinar Q0 and the plates '23 and 24 ai'e provide with a hole 38 and a pin 39 is assed through one of the holes 37 and the liole 3S so that the member 34 becomes locked to the easing and thereby forms a part of thc driving member which, upon being rotated by the shaft 12, drives the driven member 2 through the resilient; connectingr means or spring 30, one cud of which spring is connected to the driving member by pin 35 and the other end to the driven member by pin 31. If it. is desired the member 27 may act` as the driving member and the member 2O as the driven member drivin the shaft 12. 'llic spring cushions su den nick turns 'given the shaft and prevents tieir being communi` cated to the dynamo 2, as would occur iii the coupling of cars and the sudden forceful ap plieation of the brakes.

The pin 39 is constructed :uid material to be sheared of a suitable size off by the memdynamo for any reason should become stopped, as by reason of n hot box therein or for any other reason. Under such circumstances, if the pin 39 or some part were not adapted to give wa it would likely cause breaking of the sha tin 710, 1Q or other parts which might then drop to the tracks and canse an accident or serious damage. The pin 39 which is thus adapted to give way under such conditions by being .slieared o, is held in place by a head 40 and a cotlcr pin 41 at tlic other end. When the pin 39 is sliearcd oil' the driving member .10 may' continue to revolve, being driven by the axle, while the members 2 and 34 will remain stationary and no torque 'will he exerted on the dynamo shaft 15. When the trouble causing stoppage of the dynamo is remedied, it is only necessary to insert a new pin 39 to put the parts into com ilete operative condition. B v removing the liolts 25, the cap plates 23 and Q4 may be removed and all the parts quickly se :irated for inspection, repair or renewal. y

arranging the member 20 with the flange 22 and providing the cap plates 23 and 2i, the same art iis a casing covering ii various parts and keeping dirtand grit t ercfrom. 'lhe pin 39 may be easilyy removed to permit the generator to he run as a motor for testing.

Although the improvements have been described in great detail with respect to one embodiment of the invention, thc invention in its broader aspects is not limited to auch details, since many changes and modifications may be made and the invention applied to other situations.
